Product Overview

The 440G-T27121 is an Allen-Bradley Guardmaster TLS-GD2 guard-locking safety switch in the 440G safety switch family. It operates as a "power-to-release" interlock: the solenoid holds a guard closed under powered conditions and releases only when power is removed. It provides two safety (normally-closed) contacts and one auxiliary (normally-open) contact for position monitoring, plus one NC and one NO solenoid contact. It mounts via M20 conduit and delivers a holding force of 2000 N (450 lb). This switch is used in safety-critical machine guarding and access control applications where positive locking is required.
